A GFR cannot be increased but treatment can help prevent it from declining. A GFR result below 60 may indicate kidney disease and usually requires additional tests. Patients may be able to limit their potential risk with changes in lifestyle, diet and medication. A GFR below 15 indicates kidney failure. At this level, the treatment options are limited to dialysis or a transplant.
